Thanks for the update, the graphics are superb as always.
Others in the comments have criticized the story. I think the plot is good, with lots of potential, but the issue is with character interactions and their personalities, that are a little lacking. MC acts like a teenager, to whom things are out of his control and just happen and not a seasoned cop, with lots of self pity, there was a funny scene were he was thinking of taking some days off... from his days off, he is already resting. I was glad that Isabella put him in his place when he tried to act like the worried parent. His overreaction at his daughter going out with friends seemed too over the top.
Amber too is a little too over the place. Complaining on how she never gets looked like that and as soon as MC is in front of her calling him a pervert and a creep... girl make up your mind. It doesnt even come out as her being a tsundere, just unstable. Most on MC lines seemed to be "no we can't, this is wrong" I get that he is hesitant to engage in activity with such a heavy taboo, but his lines become monotonous, and while he is saying that his inner monologue seems to be going full perv on both the sister and the mother, so it becomes a little annoying as the story seems to push in on direction, his thoughts agree yet he is constantly putting on the breaks. I have nothing against a slow burn were story is prioritized over sex scenes, but it came up as he just being spineless.
In the scene in bed with Amber, there seems to be a continuity error: she goes from having her tits exposed to having them covered again with the bikini and then exposed once again. It was also weird that in Antonella's flashback she talks about her mother as her landlady, not usre if a mistake or just not taking any chances with the word mother in patreon.
